PERIODIC MAINTENANCE

Disassembly Instructions
For periodic maintenance, you will have to remove the body shell to gain access to some of the parts that require
servicing. The body shell is attached with three screws on the bottom of the locomotive chassis. One screw is in the front
screw and there are two additional screws in the rear. See Figure 1 for the exact location of the screws. Next re-attach the
body shell using care not to over-tighten the screws.
Lubrication
We recommend that you lubricate as directed on page 1 every 10 hours of operation. In addition, you also should check
the motor gearbox every 25 hours. To gain access to the gearbox, remove body shell as instructed above. Next, unscrew
the screws that cover the grease box (two small Phillips-head screws in front of the motor assembly). Inspect the gears and
apply any necessary lubrication. We recommend Bachmann E-Z Lube® #99982 Grease, or equivalent. Replace the gear
box cover when complete.
Traction Tire Replacement
Our traction tires are very durable and should not need replacing very frequently. They should last hundreds of hours
under normal conditions. If they wear out prematurely, check to make sure your track joints are tight. Gaps in your track
can cause damage to the tires. To replace the traction tires, you will need to remove the side rods. There are three Hex
screws and one Phillips-head screw on each side. Note the positions of the rods and any spacers. Remove old tire if
present, clean wheel groove with any degreasing agent making sure to follow the safety and handling instructions on
the degreasing agent's bottle. Wipe dry with paper towel or clean rag. Stretch the new traction tire over the wheel
making sure that it does not twist and seats smoothly in the wheel groove. Re-attach the side rods. Test to make sure the
rods move freely before applying power to the locomotive. Check at least one complete rotation of the wheels before
applying any power. You can manually spin the flywheel on the end of the motor to make the wheels spin,.
Light Bulb Replacement
This locomotive uses an 8 volt bayonet bulb
